Evidencing the impact of dementia
Alzheimer's Society gathers and generates evidence on the scale and impact of dementia across the UK. Our evidence deepens understanding of dementia to inform solutions.
Our aim is to curate a robust, relevant and useable evidence base to deepen understanding of dementia and inform solutions that will drive change for people living with dementia now, and in the future.
Here is the collection of our evidence, which is continually evolving as our understanding and insights grow.
